FAQ

What's the APH260 Filter?

The 7-in-1 HEPA replacement filter in this listing is already combined with a pre-filter, a true HEPA filter, an activated carbon filter (with nano mineral, cold catalyst filter, photocatalyst filter, and molecular sieve attached). Just got 1 piece of the replacement filter and it's all done.

How long does it take to change the filter?

When the replacement icon lights up (PM2.5 light turn RED and keep flashing), it is a reminder to check and change the air filter. It’s recommended to replace the filter every 6-8 months for optimal use, or according to your air filter status.

How many hours on per day?(APH260 filter)

The time setting of the filter alarm light is 3500 hours (per each reset). If used for 12 hours a day, the filter is used for 290 days. However, whether the filter needs to be replaced depends on the actual use situation. For example, if the user's house has a lot of dust and pet hair, the filter dust will be more serious, and the replacing time needs to be more frequent.

The signs to show a needed replacement:

1 PM2.5 displayed on the panel has been high

2 The air outlet has a noticeable odor

3 The screen is dusty, and an evident noise appears around the slide air vent.

Where do we purchase replacement filters?

APH260 replacement filters are available on Amazon or Airthereal's website. Search APH260 filter or click the link: APH260 Filter.

Does it ship with its first filter?

There will be a filter comes with your new purifier. The original filter is wrapped in the plastic packing inside the unit. Remember to remove the plastic and install properly before use.

Is there a how-to video?

You may watch the video on YouTube: https://youtu.be/ylebGcy-gmQ.

Is it normal for the filter to last only 3 months in a 12x12 room? The first filter lasted 5 months and the second one is only at 3 months.

We think that it is the reason for the increased frequency of use. The time limit reminder setting for the filter replacement is 2500 hours (12 hours per day, 7 months). If the machine is turned on 24 hours a day, it will flash again after 105 days.
Our filter reminder is based on the number of hours the machine is used. You can judge whether it needs to be replaced according to the actual filter status. If you don't need to replace it, press the FAN and TIMER button and hold for 3 seconds to cancel the reminder. If you need further help, please feel free to contact us.

Why is there an unpleasant smell?
Reason 1:
The filter may be too dirty if not replaced for a long time. You can replace the filter to see if you still have this problem.
Reason 2:
Use the air purifier in moist conditions or water entered in the filter. You also can replace the filter to see if you still have this problem.

What's the Anion function?

Anions are particles with one or more extra electron, conferring a net negative charge to the particle. It's used to eliminate the occurrence of air-borne bacterial infections and to reduce static electricity buildup in electronics.

It speeds up the purification by absorbing pollen, dust and other airborne particles. When the anion function is on, it becomes an air ionizer that uses high voltage to ionize air molecules.

How to use Anion?

1 When the unit first powers on, the mode will be set to Anion Mode.

2 To switch on the Anion Mode, press the Anion button to activate the Anion Mode.

To switch off the Anion Mode, press the Anion button again to inactivate the Anion Mode.

What's UV-C Light?

UV-C refers to ultraviolet light with wavelengths between 200 - 280 nanometers (nm). It emits UV light to activate the titanium oxides to break down harmful viruses, bacteria and gases that HEPA and Carbon cannot capture. The UV light is installed inside the box to avoid people being exposed directly to the UV.

Airthereal Pure Morning APH260 Air Purifier has passed the ETL stringent testing requirements.

The UV-C light is rated at 50,000 hours, or slightly longer than 5 years. It's no need to replace the UV light for normal maintenance.

How to use UV-C Light?

1 To switch on the UV-C light, press the UV-C button to activate the UV-C Light Mode.

2 To switch off the UV-C light, press the UV-C button again to inactivate the UV-C Light Mode.

What's Auto Mode?

In Auto mode, the Auto Mode will glow and the unit will automatically operate depending on the current air quality index.

It will increase the fan speed to improve air quality in the room until it returns to healthy levels.

What's PM 2.5 Indicator?

PM 2.5 Indicator shows real-time PM2.5 value. After startup, it takes about 30 seconds to activate the PM 2.5 Indicator. Then the‘PM2.5’icon with blue light will be illuminated and the real-time PM2.5 value will be displayed.

Instant PM2.5 value is one of the core references for indoor air quality index (AQI).

Regarding the AQI, working modes, and lights indicators, Airthereal APH260 Air Purifiers comply with EPA regulations.

For additional Information, please reference the United States Environmental Protection Agency

(EPA): https://cfpub.epa.gov/airnow/index.cfm?action=aqi_brochure.index#particle

What's PM2.5 Sensor?

The entrance of the sensor is at the back. You could see three little holes there.

Keep surface of the sensor clean or sensitivity is affected and may fail to function properly.

Recommended cleaning is once a month for regular use.

Clean the sensor with a cotton swab.

Do NOT use detergent or any liquid in the cleaning process.

Commonly asked questions

Q: Air quality figures have remained the same.

A: The air quality sensors holes may get blocked. Clean the sensor with a cotton swab.

Q: PM 2.5 always get a red light.

A: This is a reminder to check the air filter. When this light keeps flashing, it's time to replace the filter.

Q: The numbers have been fluctuating from 3 to 12.

A: This PM2.5 sensor is very sensitive. It means the air quality is good when the value is under 12. Need to pay attention when it goes higher than 35.

Commonly asked questions

Q: How many cubic square feet does this cover?

A: Airthereal Pure Morning APH260 is CADR rated 152+ CFM, which purifies areas up to 355 sf (33m²).

Q: What is the square footage that this unit covers?

A: Up to 335 sf. 

Q: Will this purifier get rid of cigarette smoke/smell? 

A: It absorbs smoke particles to the HEPA filter under anion mode. Then the 7-in-1 true HEPA filter will filters all smokes out of fresh air. So yes, it removes the smell of smoke by catching all smoke chemicals from the air.

Q: Will this air purifier take away cooking odors?

A: Yes, it removes odors. But if you are trying to get odors off your clothes.

Q: Does this collect dog hair?

A: Yes, it works. Better to activate the anion function as well.

Q: Will these remove mold spores?

A: Yes, it will filter out the mold spores from the air. Please turn on the UV-light to kill the mold at the same time.

Q: Does the auto mode emit ozone?

A: No, Pure Morning is ozone free certified by CARB.

Why it has unusual noise while operating?

To enhance the purifying efficiency, the filter size of Airthereal Pure Morning is much larger than others. Downside is that when it captures more and more pollutants, it gets louder. There are two ways to improve the situation: one is to replace the air filter when the noise level is obviously louder. The other one is to turn sleep mode or lowest fan speed to denoise.

Commonly Asked Questions

Q: What size space does the purifier need (as in, how much empty room does it need around it)?

A: We recommend to place the unit at least 15 inches away from TVs, radios, and other electronic products. Electromagnetic interference from certain electronics may cause product malfunction.

Q: How long is the power cord?

Q: Is this dual voltage?

A: No sorry, it's AC 120V.

A:  The outlet has to be compatible with 2-Blade US polarized plug (a plug having one blade wider than the anther), with power of 110V 60Hz.

Q: Does this produce ozone?

A: No, it's ozone free. It meets the safety and quality standard and just got the ETL and CARB listed mark.

To reset the replacement alert, press the FAN and TIMER button simultaneously and hold for 3seconds.

APH260 has been tested for electrical safety and ozone emissions, and complies with the maximum allowable concentration of ozone of 0.050 parts per million by volume (ppmv) in a 24-hour period(CARB indoor air cleaning devices safety).

CARB EO Number is G-18-110

The AQI Reading reflects the air particles' quantity around. When the air fluctuates and the particles move, the sensor in the unit will detect this change and reflect it by number.

For example, if you walk around the unit, the reading will change as the air fluctuates. That’s why the reading changed when you turned on the humidifier. 

When you turn on the humidifier, it will produce the water mist. On the one hand, the water mist is particles with a relatively large diameter. On the other hand, other particles in the air will accumulate because of the water mist. Therefore, the sensor in the unit will detect this increasing change. Once the humidifier is turned off, the reading will return to normal. The AQI Reading feature of APH260 Air Purifier works properly.

The AQI Reading reflects the air particles quantity around, and it is constantly changing. When the air fluctuates, and the particles move, the dust sensor in the unit will detect this change and reflect it by number. For example, if you walk around the unit, the reading will change as the air fluctuates.

If you still have concerns, you can do a test to check whether the dust sensor can work properly. You can spray perfume towards the dust sensor to see whether its reading goes high immediately and return later. The dust sensor is on the back of the unit.

When the APH260 is processing power on,  the blue breath light of the air quality indicator will

twinkle for 30 seconds.

Once the AQI is detecting the PM2.5, the PM2.5 light will keep blue light.

When PM2.5 light turn RED and keep flashing, it is a reminder to check and change the air filter.

The wrong PM2.5 reading issue may be because the dust sensor plugged up. Here is a picture to show you where the dustsensor is. Please kindly use a cotton swab or a hairdryer to clean it to see if the problem still exists.

ADH80 comes with a 12V DC home adapter and a 12V car cigarette adapter, making it suitable for indoor and car use.

It can't work with USB now.

The power is 20W.

Normally, the noise level should be no louder than 42dB when it's at high-speed mode. This level of noise is equivalent to the sound of rain. When it's at low-speed mode or sleep mode, the noise level should be no louder than 22dB which is equivalent to the sound of dripping.

In the first place, let’s talk about how to measure the purification capacity of an air purifier. CADR (Clean Air Delivery Rate) is the international standard for measuring purifiers' effectiveness.  CADR rating is taken in CFM which stands for cubic feet per minute, or in m³/hour, which indicates how fast the air purifier can clean the air within a particular size room.

The CADR rating for Day Dawning ADH80 is 47CFM, which means air exchanges for 5 times every hour for rooms of up to 160 sq.ft. Manufacturer recommendation room coverage for this model is up to 160 ft², suitable for bedrooms, offices and small rooms, as well as for cars. (We include a car adapter in every package)

Of course, the air quality of your space matters. HEPA air purifiers are usually working against small particles and some kinds of odors, such as pollen, smoke, and dust. If you have complicated air problems, we have to deal with it case by case.

Endeavored to improve the user experience, Day Dawning ADH80 is equipped with some advanced features like PM2.5 sensor and air quality indicator, which enables it to automatically adjust working modes according to the current air status. It takes some cost but we believe this function will be super helpful to customers.

What's more, even though the machine costs a little bit more, its replacement filter needs only $19.5, which means we save a lot for the upcoming cost.

Lastly, if you do comparison, ADH80 performs much better among those desktop size air purifiers in the market, no matter for the CADR rating, the size of the unit and filter, or the features and functions.

How does ozone work?

Ozone (O3) is a powerful sterilizer. When odors, bacteria or viruses meet ozone, oxidation reactions occur and both parties are destroyed. Ozone essentially reverts back to oxygen. Therefore, even though exposing to high concentration of ozone could do harm to human and pets, it won’t last long in the air. Just remember to open doors or windows to allow ventilation for at least 30 minutes after use. Or turn on the air conditioning during the treatment if you use it in the basement. It could sterilize the air-conditioning system as well.

How to use ozone generators?

Step 1 - Clean up the pollutants

Before ozone treatments, please do some cleaning in order to remove the source of the odors. Close the windows and doors. Make sure nobody and no pets are in the room.

Step 2 - Use the timer

It's highly recommended to set the timer and leave it in the room. Treatment time can be adjustable according to the room size and air quality. If you have no clues, you can start with 15 min, and increase the treatment duration or frequency for the next time.

Step 3 - Unoccupied space ONLY

Exposed to high concentration of ozone can be harmful. Please stay outside the room being ozone treated. We include a NO ENTRY sign in the package as a gift, which can be hung on the door.

Repeat ozone treatments

You can take out your ozone generator and schedule an ozone treatment whenever you suffer from odor issues. Repeat it when air problems recurring.

Ozone Treatment Reference

Ozone Output	Area	5,000mg/h	10,000mg/h	Frequency
Car	50 ft² / 5 m²	10 min	5 min	Once a week
Bath	100 ft² / 10 m²	20 min	10 min	Twice a week
Kitchen/Laundry	200 ft² / 20 m²	30 min	15 min	Twice a week

Living Room	500 ft² / 50 m²	90 min	45 min	Once a week
Garage	600 ft² / 60 m²	120 min	60 min	Twice a week

 
 To remove tough odors, please increase treatment time and frequency until your problem solves.

If the mold on the wall is out on the open, such as visible on the wall, the the ozone will kill the visible mold on the walls as well as the spores in the air. After several uses of the ozone machine, the mold will change color...gray to white, and you can than clean it off with bleach or sodium hypochlorite.

If the mold is behind the wall, it will not be exposed to enough ozone to eliminate it. So, if possible, you would have to eliminate the mold behind the wall in order to eliminate it permanently.

If you cannot remove the mold from behind a wall, you will need to use ozone periodically to kill the spores in the air as they form. That should prevent mold from growing elsewhere.

If your house is very humid or damp, despite using a dehumidifier, mold will likely form regularly. In that case, use the ozone regularly to kill the spores in the air.

Maintenance is super easy.
1. Take out and wash the pre-filter at the back whenever it gets stuck by dust. Put it back when it's dry and that's all done.
2. Keep the unit in a cool and dry space when it's in storage.
3. The ozone plate is meant to be used for years. Only change the plate when the blue light on it gets much weaker than before and you could smell the ozone is much less as well. The ozone plate replacement is available for sell on Amazon and our website.

Clean or change the ozone plates if the ozone output is weak. Environmental factors affect the duration of ozone output. Unscrew the four screws on both sides of the machine. Press the handle, loosen the ozone holder, and draw out the ozone plate, clean it with water or replace it with a new one, make sure the plate is dry and the metal terminals contact well.

DO NOT smell the around the machine while it's on. Only leave it on when no one is around, concentrated ozone destroys your lungs!

The max size space for which this unit is suitable is 1000sqft.

Appropriate use of ozone generator does NOT affect plants. Just don’t place the plants in front of the air outlet.

It would likely help with cooking odors, however, this ozone machine puts out unhealthy levels of ozone, so you should never run it when people and pets are going to be present. There are ozone machines that emit safer levels of ozone, which could be in operation constantly, and which would more likely help with the odor problem. That said, it would be best to experiment with the lowest level of ozone output at first to see if it is irritating.

Yes, sure. It can sterilize your air conditioning system as well.

Yes, you can stay in other room if you close doors and windows of the room being ozone treated. Just make sure all remain ozone reverts back to oxygen or thoroughly air out before you return to the room.

Airthereal Ozone Generator is equipped with an ozone plate inside the unit. Its service life can reach more than 5,000 hours. That means you don't have to replace a new ozone plate within years even though you use the unit every day. Besides, Airthereal ozone plate replacements are available for sale. Search Airthereal ozone plates and you will find it. Clean or change the ozone plates as follows if the ozone output is weak. Environmental factors affect the duration of ozone output. Unscrew the four screws on both sides of the machine. Press the handle, loosen the ozone holder, and draw out the ozone plate, clean it with water or replace it with a new one, make sure the plate is dry and the metal terminals contact well.

You can leave the food in the room when in use as long as you use it appropriately. Please don't put the food in front of the air outlet.

Please use a extension outlet when you run ozone generators inside the car. It needs to be plugged into an outlet. Turn anticlockwise to set 'HOLD', which could keep it runing. But please make sure no people are around when it's on.

If you need to set the timer to 10 minutes, you need to put timer on 40 minutes and then back to the 10 minute position.

I have to remind it again: please never run it when people, pets or plants are going to be present. It would be best to experiment with the lowest level of ozone output at first to see if it is irritating.

Many customers reported that the ozone generator is good for keeping the mustiness away in the basement.

Here are the points to note when using ozone machine in basement:

1. Turn on the air conditioning during the treatment if you use it in the basement. It could sterilize the air-conditioning system as well.

2. You only need the ozone in the basement won't vent out and exposing to your family. Also, have to thoroughly air out all remaining ozone before you return to the basement. If you believe they are not able to make it air out thoroughly, please allow a longer time to consume the residual ozone before returning to the room. Normally, the ozone will need 4 hours to react and disappear completely, but depending on the ventilation.

3. If you can't smell the ozone when you are upstairs, you don't need to block heat or cold air duct return registers. Ozone can sterilize it as well.

4. If you need further assistance, please feel free to reach out to us at support@airthereal.com.

This produces ozone which is different from negative ions. You can stay in a room with a device that produces negative ions; whereas,. you cannot stay in a room with one that generates ozone (O3). This particular unit generates a lot of ozone for its size and price.

Yes, this could be used within the range of 110V-240V.

Airthereal B50 Mini Ozone Generator is for ozone only, with adjustable ozone output switch. Perfect odor remover for small rooms such as toilets.

This works better in small areas like toilets or wardrobes. For some tough smells in large rooms, we recomend you to use Airthereal MA5000 instead. Here is the link for your convenience: MA5000 Commercial Ozone Generator

No, sorry. This is for air treatment only.

Thank you for your question. Airthereal B50 is not with a timer. You can turn it on and adjust the ozone output when you need it.

Sorry, it's in 110V. You would need a power converter if your power supply is 220V.

The unit will begin producing ozone when you press the power button. But, it starts with its minimum ozone output of 2g/h. Although ozone impacts our body through breathing, the low concentration of ozone environment has little effect on human injury. Please don't worry too much. You can hold your breath when setting the timer and leave the room right away.
